Hydride ion (H-) is an anion which is formed when an hydrogen atom gains an extra electron. The electronic diagram of hydride ion is:

Hydride ion is usually found in the ionic hydrides of reactive metals, e.g. KH, NaH and CaH2­. These hydrides are strong bases, unstable, and would react with water to give hydrogen gas.
e.g. NaH(s) + H2O(l) → NaOH(aq) + H2(g)

Such metal hydrides are included in the part of inorganic chemistry in HKAL.

"H-" 是 "Hentai&;quot; 的縮寫, 日文意思是"變態"

樓上d人有病=.=? 人地問緊化學 唔係問你變態唔變態...

hydride ion既然少見 咁佢一定唔會穩定
所以其實佢係一個好唔穩定的化學品

佢一般會以 LiAlH4 出現於有機化學入面的還原劑
將organic acid轉做alkanal / alkanol

H-GAME全個我就知點解(成人遊戲), 但係個H-係點解我就唔係好清楚, 我THINK係high咁解, 玩到好high個種game 就叫h(high)-game........這是我個人的認為, 我錯的請說 以前好少咸 game的, 只有在機鋪的美女麻雀脫衣game, 同而家d機鋪見到的麻雀一樣係好多鍵的, 以前的按鍵係排到好似"H-"型咁的, 所以就沿用至今了.... 常玩咸game朋友

色情既動畫/漫畫呀!因為我之前都見過某D漫畫網站見過..所以記得xP你試下搜尋下呢兩個字眼啦..就會知道係乜..=v="同埋,我其實都不清楚"H-";點解呀..我諗大家要睇多D色情野先知係乜了..=_=(幫唔到你,抱歉Ha) myself

H-Game,這個"H-";呢,其實是由日本來的。因為在日本,色色的事物叫做...henijokodo。所以啦,只要看到有"H";字樣的遊戲,差不多就是這個意思。本站提供站長搜集的hgame遊戲,包含介紹、試玩、下載...等。
